Last year, Washington and Athens agreed to deploy US drones to the Larissa Air Force base in Greece. The allies are currently considering deploying US F-35 fighter jets to a base in the Greek city of Volos.

Washington and Athens conducting a joint live-fire exercise at the foot of Mount Olympus in January is "the latest sign" of the US military expanding its presence in Greece, The Wall Street Journal (WSJ) reports.

The newspaper cited Greek Brigadier General Georgios Fasoulos, who observed the exercises, as saying that the Athens-Washington alliance equally meets the interests of both sides.
